Imagine that you have a voltage source in series with some source resistance feeding power to a variable load. The relationship between load voltage, load current, and cell current can be drawn...
The recent Design Idea “Getting an audio signal with a THD < 0.0002% made easy” discloses a low THD sine generator which led me to dust off a design...
Texas Instruments introduced the world's smallest MCU, expanding its comprehensive Arm Cortex-M0+ MSPM0 MCU portfolio. Measuring only 1.38 mm2, about the size of a black pepper flake...
It’s remarkable how many switching regulator chips use the same basic two-resistor network for output voltage programming...
From the micromixer topology by Barrie Gilbert, this amplifier allows a single-ended input to be converted to a Class A/B current output from a single supply...
Initially imagined by Nikola Tesla in the early 1900s, the concept of a world wide web didn’t see creation until 60 years later. Take a trip alongside the history of the internet...
This design idea reprises another “1 A, 20 V, PWM controlled current source”. Like the earlier circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, 1 A current source...
STMicroelectronics has introduced the Teseo VI family of global navigation satellite system receivers aimed at high-volume precise positioning use cases...
Traditionally, the reception quality of a digital receiver is expressed in terms of BER. This figure is the proportion of received bit errors in a given period...
